PLC circuit board conveying device and conveying method

Abstract

The invention relates to the field of PLC circuit boards, and discloses a PLC circuit board conveying device. The PLC circuit board conveying device comprises a circuit board conveying rack, a circuitboard conveying sliding groove and a circuit board shifting mechanism, wherein the circuit board conveying sliding groove and the circuit board shifting mechanism are fixed to the circuit board conveying rack; the conveying rack is fixed to a workbench; the circuit board conveying sliding groove is matched with a plurality of PLC circuit boards, and the circuit board conveying sliding groove is connected with an electrostatic eliminating device, a circuit board washing device, a circuit board drying device and a circuit board overturning and air-drying device; the circuit board shifting mechanism is in contact with the PLC circuit boards and is connected with the circuit board conveying sliding groove; the circuit board conveying sliding groove is used for embedding a plurality of PLC circuit boards; and the circuit board shifting mechanism is used for shifting the plurality of PLC circuit boards to be conveyed forwards. By arranging the circuit board shifting mechanism, the size of the whole conveying device is reduced, and the occupied space of equipment is reduced.

Description

technical field [0001] The invention relates to the field of PLC circuit boards, in particular to a PLC circuit board conveying device, a conveying method and cleaning equipment. Background technique [0002] The PLC circuit board is the provider of the electrical connection of electronic components. The use of the PLC circuit board can greatly reduce the errors of wiring and assembly, and improve the level of automation and labor productivity. In the circuit board welding assembly, after the components on the PLC circuit board are installed through various welding processes, a certain amount of residue will remain on the component pins on the panel due to flux, solder and environmental influences. These residues directly affect the quality of the product, must be cleaned to ensure the electrical performance indicators of the PLC circuit board, and ultimately ensure the stability, reliability and working life of the electronic product, so the cleaning of the PLC circuit boar...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When conveying the PLC circuit board, the lever is first moved down to the side of the PLC circuit board, and then the moving device drives the lever to move so as to drive the PLC circuit board to move forward, and the PLC circuit board moves forward and then dials The lever is retracted vertically to avoid touching the PLC circuit board; and there are many electronic components on the PLC circuit board, when there are electronic components with a higher height on the PLC circuit board, the vertical retraction of the lever needs to be moved higher The height of the whole conveying device is larger, which increases the occupied space of the equipment.

2. When the surface of the PLC circuit board is air-dried for the second time, it is only air-dried by rotating the PLC circuit board; when the PLC circuit board is only rotated, the PLC circuit board only moves in the horizontal direction; The cleaning agent between the components is blocked in the horizontal direction, and cannot flow out when the PLC circuit board moves horizontally, resulting in insufficient drying of the PLC circuit board when it is air-dried for the second time, affecting the cleaning quality of the PLC circuit board
